Transcript and Presenter's Notes

Title: Primary Productivity


1
Primary Productivity
2
Effect
  • The effect of abiotic factors(wind, currents,
    topography and dissolved nutrients
  • ON
  • Biotic processes (photosynthesis)
  • Measured by
  • dissolved O2 levels (obs)
  • Chlorophyll concentration (satellite)
  • Temperature (obs)

3
Background
  • Photosynthesis
  • Trophic Levels
  • Chemistry (dissolved oxygen)
  • Earth Science (topography, currents)
  • Physics (wind, energy transformations)

4
Activity
  • Take a given geographic location (Monterey Bay)
    and find two areas to compare productivity High
    verses low.
  • The more diverse the better. Use satellite data
    for color images to determine areas

5
Why is there a difference?
  • Possibilities
  • Look at wind patterns (obs)
  • Look at currents (obs)
  • Look at topography (GIS)
  • Look at dissolved nutrients (LOBO)
  • Look at surface temperature (obs)

6
Hypothesis
  • Is there data to support the differences and what
    would the Hypothesis be.
  • What is the explanation?
  • (eg. Is cold temperature related to
    productivity?)
  • Is temperature related to upwellings/currents?

7
Confirmation of Satellite Images
  • Chemistry
  • Dissolved O2
  • Dissolved nutrients phosphates, nitrates

8
Further Analysis
  • Graph dissolved O2 vs. sunlight
  • Graph O2 vs. depth
  • Graph productivity vs temp
  • Look at algal blooms and nutrient runoff
  • Ecosystem energy movement
  • Sun Producers
  • Breakdown by bacteria
